Option C, They allow random distribution of genetic material when a cell divides.
Explanation:
The chromatin are responsible for packaging of DNA molecule into smaller space with in a chromosome. It not only package it but also protect it from. Packaging allows for easier division of cells during mitosis and meiosis and hence prevent any kind of damage to the DNA.
Chromosomes make recombination and random segregation of genetic material to form new cells. Each new cell gets equal number of chromosomes
The first thing that will happen is the competition between the new and old species. The new species will likely have no predator and will be better capable of survival and will be more aggressive than native species. The competition will dramatically decrease the population of native species, maybe even drive them to extinction. This will destroy the habitats biodiversity
